The Yb-doped potassium yttrium tungstate (Yb:KYW) crystal, in comparison to its counterpart Yb:KGW, is often a remarkable materials that plays a very important role in laser engineering. Its Key functionality would be to make ultrashort pulses of sunshine, spanning only a few hundred femtoseconds.

time. Crystals of the compound melts congruently at 1007 oC, nonetheless melt crystallization of top of the range crystal is unattainable as a result of stage changeover at ~920 oC. The highest seeded solution method from

This paper describes a femtosecond laser regenerative amplifier determined by two Yb:KYW crystals with immediate longitudinal pumping by powerful linear arrays of semiconductor injection lasers owning fiber output. To avoid spectral narrowing for the duration of amplification and the corresponding lengthening of the amplified pulse when it can be compressed, a combination of two Yb:KYW crystals were being utilised, While using the spectral maxima with the amplification shifted relative to each other and with spectral profiling of your amplified radiation.

The monoclinic crystal structures leads to a pure birefringence, assisting to stay clear of thermally induced polarization rotation and depolarization loss.

Raman, luminescence and transmission spectra expose optical functions owing to the existence of thulium ions, and so the supplies could be even further researched during the scope of laser and luminescence apps.

five mm besides the middle of your beam caustic. In an effort to Look at the manner matching simulation, we executed the experiment with Ng-Lower crystal oscillator, which was developed Earlier and in a exact same situation with simulation [eleven]. As shown in Figure three(b) with red dots and line, the CW output ability is extremely depending on the position of laser crystal plus the experimental result coincides properly with simulation final result. As being a Observe, multimode Procedure occurred in experiment once the size on the pump beam is larger sized than TEM00 cavity mode and it brings about better CW output energy inside the displacement area underneath three.five mm.

Superior-energy repetitively pulsed ytterbium lasers with supershort pulse width and direct diode pumping for technological and biomedical apps

Whilst ytterbium-doped laser acquire media normally show a small quantum defect, ytterbium-doped tungstates let for especially tiny values. As an example, a 1030-nm Yb:YAG laser would Generally be pumped all-around 940 nm, While Yb:KGW or Yb:KYW may very well be most effectively pumped all-around 981 nm.

Li2WO4-WO3 flux was properly utilized minimizing the growth temperature beneath 900 oC. According to one crystal x-ray measurements, the crystal corresponds to the P2/n Place group.
